Author Affiliations +
We have fabricated pentacene organic thin-film transistor (OTFT) driven active matrix organic light-emitting diode (OLED) displays on both glass and flexible polyethylene terephthalete (PET) substrates. These displays have 48 × 48 bottom-emission OLED pixels with two pentacene OTFTs used per pixel. Polyvinyl alcohol (PVA) and parylene were used to photolithographically pattern the pentacene active layer and isolate the OTFT backplane from the OLEDs. Pentacene OTFTs are able to easily supply the current required for OLED operation, but improvements in device uniformity and stability are of interest.
